It was motivated by the growing recognition of the need to modify bidding operation previously done manually. The Structured System Analysis and Design Methodology (SSADM) was used to develop a contract bidding system. A web – based application will be developed to enable bidders register and submit their biddings online.</p> Emmanuel Nwabueze Ekwonwune Duru Ngozi A.

The aim of this work was to extract out the information required to re- implement the Legacy programs in a new client/server environment. The progress solution is in four step. Firstly, the programs were restructured, secondly the programs were sliced into business logic modules, third the business modules were subjected to a multi view analysis and finally the views were integrated into a unified documentation describing the data, decision and procedural flow of each program slice.</em></p> Emmanuel Nwabueze Ekwonwune Egwuonwu Deborah I ##submission.copyrightStatement## 2019-05-12 2019-05-12 8 05 24621 24628 10.18535/ijecs/v8i05.4317 Analytical Assessment of Poultry Feed Production in Animal Husbandry <p><em>The cost of Poultry feed represents over 70% of the total cost of poultry production in Nigeria and elsewhere in the globe. This has however not reduced interest shown in poultry agriculture in recent times as contributions from this sector have impacted positively on national economy.&nbsp; Efficient formulation regime devoid of inefficient feed production practices is required for poultry husbandry sustainability. This paper aims to make an analytical assessment of poultry feed production in animal husbandry in Nigeria with a view to finding out how each of the examined methods has helped the growth of this all important industry. The objective is to recommend a software that can solve mixing or blending problem facing a poultry farmer while using locally available feed ingredients at his disposal. It is hoped that the choice method shall minimize cost of producing a particular feed without compromising its adequacy as a balanced diet, which will in turn reduce the cost of overall production of poultry birds. The methodology employed in this paper is </em><em>Structured System Analysis and Design Methodology (SSADM). A top down Software design approach was followed.</em><em> The expected result included affordable and acceptable poultry feed production modelling system that grants a high return on investment (ROI) to the poultry farmer. The research work shall be useful to the present and upcoming poultry farmers, who would want to take poultry agriculture as an entrepreneur. It would also encourage further research in this area of study.</em></p> <p><strong><em>&nbsp;</em></strong></p> Emmanuel Nwabueze Ekwonwune Edebatu Dominic C.. ##submission.copyrightStatement## 2019-05-12 2019-05-12 8 05 24629 24644 Analytical Assessment Of The Negative Impacts Of Marijuana Smoking On Human Population <p><em>Smoking is a practice in which a substance most commonly called cannabis is burnt and the smoke tasted or inhaled. The aim of this work is to design software that will predict the negative impact of marijuana smoking on consumers. This will help in recognizing the consequences of smoking marijuana and abuse on physical and mental health as well as socio-occupational life and also act as a necessary step for initiating appropriate action to reduce the harm/danger from smoking. This work was motivated by the observed and anticipated negative health burden with its concomitant socio- economic consequences which the nation is bound to face, if systematic efforts are not made now to control the growing problem of marijuana smoking. The methodologies for the execution of this research work were the statistical analysis of a sample population of people treated at the Imo State teaching hospital (IMSUTH from diseases emanating from marijuana smoking using Statistical Packages for Scientific Studies (SPSS) and deployment of the relevant coefficients from the analysis to develop a systematic forecasting software model used in simulating for the next 30 years. The simulation is intended to be predictive and to enable policy makers to see the impact and dangers of marijuana smoking between now and the next 30 years if current abuse is not controlled .That is the number of smokers likely to contact liver, brain and related diseases and who are most likely to die from these diseases. The software provides approximate prediction of likely deaths that may occur via diseases such as: liver, brain damage, heart and hypertension</em></p> Emmanuel Nwabueze Ekwonwune Dennis Mary C. ##submission.copyrightStatement## 2019-05-12 2019-05-12 8 05 24645 24654
